Application November 17, 1947, Serial No. 786,391

This invention relatesto new and useful improvements in lamps and the primary object of the present invention is to provide a portable lamp so designed as to facilitate, a lamp bulb to be quickly and readily applied to or removed from the same in a convenientmanner.

Another important object of the present invention is to provide a portable lamp for mechanics and the like including noveljand improved clamping means for attaching the same to a suitable structural element or support.

A further object of the present invention'is to provide a lamp reflector including novel and improved means carried by the same that will support. the reflector relative to a supporting surface without movement during use.

A still further aim of the present invention is to provide a portable lamp that is simple and practical in construction, strong and reliable in use, small and compact in structure, neat and attractive in appearance, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

' Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a perspective view of the portable lamp constructed in accordance with the present invention, and with dotted lines showing a lamp socket applied thereto;

Figure 2 is a longitudinal vertical sectional view taken substantially through the center of Figure 1;

Figure 3 is a transverse vertical sectional view taken substantially on the plane of section line 33 of Figure 1; and

Figure 4 is an enlarged fragmentary side elevational view of the clamping means used in conjunction with the present invention.

Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed the preferred embodiment of the present invention, the numeral I represents the reflector of the present portable lamp, generally, having a flat bottom wall I2 supporting an insulating pad 13, arcuate side walls 14 and IS, a rear open end wall l8, and an enlarged forward end wall 28. Fixedly secured to the outer edges of the walls l4, l6 and I8, is a substantially U-shaped bearing flange or strip 22.

Hinged as at 24 to that portion of strip 22 adjacent the wall [4, is one longitudinal bar 1 Claim. (Cl. 240-54) 28 of an open frame or channel-shaped guard that is designated generally by the numeral 28. The opposite end or longitudinal bar '38 of this guard is provided with projecting eyes or loops 32 that engage a screw-threaded rod 34 adjustably carried by a suitable aperture provided in an outwardly projecting ear 36 rigidly secured to Wall [6, and to that portion of the strip 22- that opposes wall It. A wing nut or the like 28' ad-justably mounted on the rod 34 bears against the eye 32 for retaining the guard in a lowered or closed position relative to the reflector H).

Projecting outwardly from the rear wall 18 of the reflector, is a substantially channel-shaped projection 40 that terminates in an arcuate strip 42 having an attaching flange or ear 44. Hinged to one edge of the strip 42, as at 46, is one edge of an upper complementary arcuate strip 48 also having an ear that opposes ear 44. These ears 44 and 50 are adjustably connected by a fastener 52. The inner edge of the upper strip 48 is provided with a flared shield 54 that 0pposes the opening 58 in the projection 40.

Rigidly secured to the outer peripheries of the walls l4 and 16, adjacent wall l8, are the inner edges of a pair of arcuate fins or cams 58 that prevent damage to the hinge 48, the ear 38 and the loop 32 in the event of rolling of the reflector.

Fixed to the forward wall 20 of the reflector is a lug 60 having a bearing plate 62 at one end that bears against the inner face of wall 28, and a spherical element or member 64 at its outer and opposite end.

The numeral 66 represents the clamping member used in conjunction with the present invention generally, comprising an upper jaw 68 and a lower jaw 10. These jaws B8 and if! are provided with opposed toothed gripping surfaces 12 and 14. Integrally formed with one end of t the jaw 68 is an attaching plate I6 that engages the upper periphery of the member 64. This plate 16 is adjustably connected to a further attaching plate 18 that frictionally engages the lower periphery of member 64, by a fastener 80. The free ends 82 of the plates 16 and 18 are flared toward each other to retain the same relative to the member 64.

The outer end of plate 10 is provided with enlarged extensions 82 having slots 84 that slidably engage pins 86 connecting the enlarged inner portions 88 of the lower jaw 10. The jaws 68 and 10 are adjustably connected by a fastener 90 on which there is loosely positioned a coil spring 92 that normally retains the jaws 68 and spread relative to each other. The slidable connection between the jaw I0 and the plate '18 will retain the jaws spaced parallel to each other at all times to aid in frictionally attaching the device with equal gripping tension relative to a supporting structure.

Rigidly secured to one of the jaws, preferably jaw 68, is one end of a hooked element 94 that will permit the lamp to be applied to a suitable support to depend or hang therefrom.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claim.

Having described the invention, what is claimed as new is:

A portable lamp comprising an elongated reflector having a flat bottom wall for resting upon a supporting structure and a pair of side walls, a pair of vertical fins fixed to and projecting from the side walls of said reflector, said reflector being tapered at one end and said fins being disposed adjacent the tapered end of said reflector, said reflector including a forward wall said forward wall and said side walls each having upper edges, a substantially U-shaped bearing flange fixed to the upper edges of said forward wall and said side walls, a wire frame hinged to one side wall of said reflector and including a substantially U-shaped portion for resting upon the U-shaped flange, means for securing the frame to the reflector with the U-shaped portion of the frame against the U-shaped flange, and means at the tapered end of said reflector for supporting a lamp within the reflector and the frame, said fins preventing damage to the hinge of the frame and the securing means in the event of rolling of the reflector.
